Knee Joint Replacement: When Is It Necessary?
- Knee joint replacement is a significant medical procedure designed to alleviate severe and debilitating knee pain and disability.
- This treatment is often considered when conservative methods, such as medication, physical therapy, and injections, no longer provide sufficient relief.
- Let's delve into the conditions that necessitate knee joint replacement and understand the process, symptoms, and treatment involved.
Common Conditions Requiring Knee Joint Replacement
- Osteoarthritis: This degenerative joint disease wears away the cartilage in the knee, leading to pain, stiffness, and reduced mobility.
- Rheumatoid Arthritis: An autoimmune condition that causes inflammation and damage to joint tissues, resulting in pain and deformities.
- Post-Traumatic Arthritis: Follows severe knee injuries like fractures or ligament tears, causing accelerated joint degeneration and chronic pain.
- Knee Deformities: Congenital or acquired deformities can lead to uneven pressure distribution, causing progressive joint damage.
- Avascular Necrosis: Disruption of blood supply to the bone leads to bone death and joint damage.
Symptoms Indicating the Need for Knee Joint Replacement
- Persistent Knee Pain: Chronic, unrelenting pain, especially during movement or weight-bearing activities.
- Limited Mobility: Difficulty bending or straightening the knee, leading to a reduced range of motion.
- Stiffness: Tightness in the knee joint, particularly after periods of inactivity.
- Swelling: Persistent swelling around the knee, often with warmth and tenderness.
- Functional Limitations: Difficulty performing daily activities like walking, climbing stairs, or getting up from a chair.

Knee joint replacement surgery, or knee arthroplasty, is a surgical procedure in which the damaged or diseased parts of the knee joint are replaced with artificial components (prosthetics) to restore joint function and alleviate pain.
Knee joint replacement is typically needed when individuals experience severe and persistent knee pain, limited mobility, and functional limitations due to conditions like osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, knee deformities, or avascular necrosis.
If you have chronic knee pain, stiffness, swelling, and difficulty performing daily activities, it's essential to consult an orthopaedic specialist. They will conduct a thorough evaluation, including a physical examination and imaging studies, to determine if knee joint replacement is appropriate for your condition.
The recovery period varies for each individual, but most patients can expect to resume light activities within a few weeks after surgery. Complete recovery may take several months, including returning to more demanding physical activities.
Modern knee joint replacements are designed to be durable and long-lasting. While they may not last a lifetime, they can provide relief and function for 15 to 20 years or even more with proper care and appropriate physical activity.
Most patients can begin light activities and walk within a few weeks after surgery. However, it's essential to follow the rehabilitation plan provided by your healthcare team and avoid high-impact activities until you receive clearance from your orthopaedic surgeon.
